Dornoch Castle is situated opposite Dornoch Cathedral in the town of Dornoch, in Sutherland, Scotland, a little over 40 miles (64 km) north of Inverness.

As of 2021, the castle was operated as a family-run hotel with 24 rooms.

Dornoch Castle was built around 1500 as the home of the bishops of Caithness. Bishop Robert Stewart gifted the castle to John Gordon, 11th Earl of Sutherland in 1557. In 1570 the castle was set alight in a feud between the McKays and Murrays. The rebuilding which followed included the addition of the upper part of the tower. The Castle is believed to have been haunted by the ghost of the covenanter, Andrew McCornish, who was hanged for sheep stealing in the 17th century.

The castle decayed during the 18th century, but was restored between 1813 and 1814. In the first half of the 19th century, court hearings were held in a room in the tower of castle, accessed by a spiral staircase, until Dornoch Sheriff Court was erected further to the east along Castle Street in 1850. Following extensive remodelling by William Fowler, the castle became a residence for George Sutherland-Leveson-Gower, 2nd Duke of Sutherland, in 1859.

Further alterations were made around 1880, including the heightening of the south-west block, and the addition of a three-storey east tower.

The castle was sold to a private developer in 1922 and was converted into hotel in 1947. Facilities included 24 bedrooms, and some garden rooms, which were added in the 1970s. The castle is a category B listed building.
